Foster gave Forest City, Iowa-based Winnebago and Knott until Aug. 13 to propose an order to implement his July 25 ruling. The judge said he would consider a request to defer the ban on Knott’s use of the name for a “reasonable time” to allow the company to rebrand its business.

“I urge the parties to agree on an appropriate period for this rebranding to occur,” Foster wrote. “In the event that agreement cannot be reached, I will determine the appropriate period.”

Knott had no comment on the ruling today, said the person who answered the phone at the company’s office and declined to be identified.

Binns founded Emu Plains, New South Wales-based Knott in 1967 as a landholding company that acquired properties for recreational vehicle factories in Australia. The manufacturing company, Freeway Camper Co., failed and was wound up in 1977, Foster wrote.

Knott then began manufacturing recreational vehicles and selling them under the Winnebago name, either in 1978 according to Binns, or 1982, according to Winnebago, Foster said.
